Retransmissions can be scheduled, thereby allowing fast retransmissions. If the symbol carrying the uplink control information is not indicated by using the first information and the uplink control information is transmitted only in the last symbol of subframe n in a predetermined manner, the processing time Since it is not reserved, the base station cannot schedule retransmissions in subframe n + 1, and the earliest time that retransmissions can be scheduled is in subframe n + 2, thus increasing the delay.
